Extracting gold from old phones and laptops

Instead of harsh chemicals, the team used TCCA to dissolve gold from things like circuit boards and phones.
Then, a special polymer grabs just the gold and releases it as pure metal when heated—making recycling much easier.

This approach cuts down on pollution and helps recycle precious metals from e-waste, which means less harm to the planet and smarter use of old tech.
Researchers hope it'll inspire greener ways to mine and recycle in the future.
